A Rapid Method for Controlling and Measuring Projection Deformation in Substations
Traditional substation control surveying and mapping adopts triangulation,traverse surveying and satellite positioning surveying,which usually requires two more personnel and a large amount of surveying instruments on site.Moreover,traditional control surveying methods are time-consuming and labor-intensive,making it difficult to meet re-quirements when the project schedule and personnel are tight.This paper introduces a rapid projection deformation cal-culation method used in substation control surveying.This calculation method projects other points in the control network to the target projection height by selecting a projection origin,thus achieving the purpose of rapid control projection.This rapid projection method is more than traditional control surveying methods,providing a new working method for the"single soldier operation"mode of substation full-process surveying and mapping.
